Between same-sex marriages and the Large Hadron Collider: making sense of the precautionary principle.

The Precautionary Principle is a guide to coping with scientific uncertainties in the assessment and management of risks. In recent years, it has moved to the forefront of debates in policy and applied ethics, becoming a key normative tool in policy discussions in such diverse areas as medical and scientific research, health and safety regulation, environmental regulation, product development, international trade, and even judicial review. The principle has attracted critics who claim that it is fundamentally incoherent, too vague to guide policy, and makes demands that are logically and scientifically impossible. In this paper we will answer these criticisms by formulating guidelines for its application that ensure its coherence as a useful normative guide in applied and policy ethics debates. We will also provide analyses of cases that demonstrate how our version of the principle functions in practice.

Good ethics can sometimes mean better science: research ethics and the Milgram experiments.

All agree that if the Milgram experiments were proposed today they would never receive approval from a research ethics board. However, the results of the Milgram experiments are widely cited across a broad range of academic literature from psychology to moral philosophy. While interpretations of the experiments vary, few commentators, especially philosophers, have expressed doubts about the basic soundness of the results. What I argue in this paper is that this general approach to the experiments might be in error. I will show that the ethical problems that would prevent the experiments from being approved today actually have an effect on the results such that the experiments might show less than many currently suppose. Making this case demonstrates two conclusions. The first is that there are good reasons to think that the conclusions of many of Milgram's commentators might be too strong. The second conclusion is a more general one. The ethics procedures commonly used by North American research ethics boards serve not only to protect human participants in research but also can sometimes help secure, to an extent, the integrity of results. In other words, good ethics can sometimes mean better science.
